@pescobar For which software were you hitting this missing $CUDA_ROOT? A quick Google search seems to suggest this is software-specific (e.g. PyCUDA)?

@boegel I noticed that one of my users was hardcoding this env var in his bashrc and I thought it would be useful to define it in the module .

I thought it was a widely used env var but you are right that this is not a standard env var. Only few applications use it. I didn't notice it.

I think this PR can be discarded but it's also true that having this env var doesn't hurt

@easybuilders/easybuild-easyblocks-maintainers Thoughts on this?

It indeed doesn't hurt to let CUDA modules define $CUDA_ROOT, even though it's not standard?

awaiting feedback from @easybuilders/easybuild-easyblocks-maintainers ...

I'll go ahead and include this, under the assumption that things won't blow up.

If they do, we'll hear about it soon enough...
